TriTAG's map of the LRT (red) and planned express bus routes. The line is more interurban than it is CBD-to-suburb.

My last Record column this year evaluates the idea of the central business district in the context of Waterloo Region, and (of course) again discusses light rail. Hopefully it isn’t too unfocused:

The Future is Multi-Nodal

Commentary on the light rail transit project reveals a common but outdated assumption that a city should have a central business district (CBD) — an area of downtown that no one lives in, but many commute to from the suburbs. A frequent argument against the project is that downtown Kitchener isn’t a large enough CBD and that there aren’t enough people commuting in. But the whole concept of a central business district is a thing of the past, and light rail does not need a large CBD to make sense. The future lies in urban areas composed of multiple dense nodes connected by high-quality transportation — which happens to be exactly what Waterloo Region is planning for.

Cities once contained housing in addition to commerce and industry. When streetcar lines were started, they moved people within the city, but they also opened up the suburbs for residential development that promised tranquility and fresh air. Later, the availability of cars and cheap fuel together with massive post-war highway and road development led to suburban flight on a larger scale. Commerce also followed the highways and set up shop in suburban malls. Only jobs remained, producing the classic CBD — where commuters stay from 9 to 5, leaving an empty city every evening. But those long commutes aren’t healthy for our cities, and an office monoculture is not conducive to urban living.

Most of Waterloo Region’s growth has occurred after the post-war years, and many jobs are located in suburban office parks. So we have no reason to cling to the notion of a CBD — it just doesn’t apply. But that’s not a bad thing. Instead of jobs clustering in any single downtown, many destinations and much employment have fortunately clustered along a reasonably dense linear corridor.
